you can tame spiders (normal only, not cave) with beef.

Also, they are become unkillable when you tame them, and the collar was added using resoursepack.

I created this pack because the original mod's author has not updated it for newer Minecraft versions. (https://www.curseforge.com/minecraft/mc-mods/tameable-spiders)

Known issues

These might got fix in future

If you can't tame it with beef IN MAIN HAND, just paste in this command: /function teamable_spiders:load in to game chat.

For some reason, Minecraft in some cases may not run "load" function on it's own, even though it has to. This function makes a really important stuff, especially for 1st loading in-game.
